If I had to guess, it will be a continued redesign of the browser, possibly with an update of the design of the Speed Dial page. It seems Opera is trying to operate somewhere in the middle of Chrome and Vivaldi. Whereas Chrome is very basic and relies on Web Store extensions/themes to bring you greater customization options, Vivaldi takes it in the exact opposite direction to the point it can be somewhat confusing for non-power users. Opera seems to be trying to gobble up people who might want more baked in options and features, but are put off my so many options on Vivaldi (fair or unfair as that may be).
